BAOS SDK v2  1.0.1
An SDK providing access to IP-BAOS devices through BAOS binary protocol version 2.x
ServerItemIndication.cpp

This sample shows how to register a callback function for server item indications via the connection API.

Usage:

ServerItemIndication <ip_address>
// e.g.:
ServerItemIndication 10.0.0.102
